Definitions

  • the present invention relates to a production method of ether compounds which are useful as active ingredients of insecticide/acaricide or production intermediates thereof.
  • the publication also concretely discloses a production method of 1-benzyloxy-3,5-dichloro-4-[3-(5-trifluoromethylpyridin-2-yloxy)propoxy] benzene (the compound given by above formula (2) wherein R 2 is a hydrogen atom) by making 3-(2,6-dichloro-4-benzyloxy)phenoxy-1-propyl alcohol react with 2-chloro-5-trifluoromethylpyridine in the presence of a base in N,N-dimethylformamide.
  • the object of the present invention is to provide a production method of the ether compounds given by formula (3): wherein R 1 represents a benzyl group optionally substituted with a halogen atom(s) or 3,3-dihalo-2-propenyl group and R 2 represents a hydrogen atom or halogen atom, in high yield by using a hydrocarbon compound that is industrially available as a solvent.
  • the ether compound given by formula (3) can be produced by making the alcohol compounds given by formula (4): wherein R 1 represents a benzyl group optionally substituted with a halogen atom(s) or 3,3-dihalo-2-propenyl group, react with the pyridine compounds given by formula (5): wherein R 2 represents a hydrogen atom or halogen atom, in a hydrocarbon compound in the presence of alkali hydroxide or alkaline earth hydroxide with distilling off water from the reaction mixture in high yield and good quality.
  • the benzyl group optionally substituted with a halogen atom(s) for R 1 means a benzyl group or a benzyl group whose hydrogen atom(s) on the benzene ring is/are substituted with at least one halogen atom.
  • Typical examples include benzyl group and 4-chlorobenzyl group.
  • Examples of the 3,3-dihalo-2-propenyl group for R 1 include 3,3-dichloro-2-propenyl group and 3,3-dibromo-2-propenyl group.
  • halogen atom for R 2 examples include chlorine atom.
  • the production method of the present invention is characterized by making the alcohol compound given by formula (4) react with the pyridine compound given by formula (5) in a hydrocarbon compound in the presence of an alkali hydroxide or alkaline earth hydroxide with distilling off water.
  • the reaction is carried out in a hydrocarbon compound.
  • the hydrocarbon compound used for the reaction include aliphatic hydrocarbon compounds such as hexane, heptane, octane, nonane, decane, 3-methylpentane, cyclohexane, methylcyclohexane, ethylcyclohexane and so on; and aromatic hydrocarbon compounds such as toluene, xylene, mesitylene, ethylbenzene and so on.
  • hexane or heptane is used as the hydrocarbon compound.
  • the amount of the hydrocarbon compound used for the reaction is usually 0.3 to 50 parts by weight based on 1 part by weight of the alcohol compound given by formula (4), preferably 10 parts by weight or less in the view of the reaction rate.
  • the ratio of the alcohol compound given by formula (4) to the pyridine compound given by formula (5) used for the reaction is usually 0.9 to 2 mols of the pyridine compound given by formula (5) based to 1 mol of the alcohol compound given by formula (4).
  • alkali hydroxide and alkaline earth hydroxide used for the reaction examples include lithium hydroxide, sodium hydroxide, potassium hydroxide, calcium hydroxide and barium hydroxide.
  • the amount can be varied so long as the reaction proceeds, and it is usually 0.9 mol or more based on 1 mol of the alcohol compound given by formula (4) and 1.2 mols or less based on 1 mol of the pyridine compound given by formula (5).
  • the alkali hydroxide and alkaline earth hydroxide used for the reaction can be added to the reaction mixture as an aqueous solution.
  • the reaction temperature is in the range of 50 to 200°C and the reaction can be carried out under reduced pressure so that water can be easily distilled off from the reaction mixture.
  • the distillation of water is performed while the reaction is proceeding.
  • the method for distilling off water from the reaction mixture is, for example, 1) performing the reaction at the boiling point of water or more under normal pressure or reduced pressure and distilling off water from the reaction mixture or 2) performing the reaction at the boiling point of the solvent or more under normal pressure or reduced pressure and distilling off water together with the solvent from the reaction mixture.
  • the solvent can be recycled by using Dean-Stark water-separator and separating the solvent from water in the distillate.
  • the reaction can be carried out as follows.
  • the proceeding status of the reaction can be confirmed by analyzing the reaction product with chromatography such as high performance liquid chromatography and the like.
  • the ether compound given by formula (3) can be isolated by work-up procedures, for example, adding water to the reaction mixture, extracting with an organic solvent and concentrating the obtained organic layer.
  • the ether compound given by formula (6): wherein R 2 represents a hydrogen atom or halogen atom and R 4 represents a benzyl group optionally substituted with a halogen atom(s), which can be manufactured by the production method of the present invention, can be lead to a dihalopropene compound given by formula (7): wherein R 2 represents a hydrogen atom or halogen atom and R 5 represents a 3,3-dihalo-2-propenyl group, for example, according to the method described in USP-5,922,880.
  • the alcohol compound given by formula (4) can be prepared by the method disclosed in USP-5,922,880 or according to the description of USP-5,922,880.
